I got a problem with my cdj 900s guys, need help..

[Stefan999]

I put the usb stick in the cdj 900, started playing music, everything was doing well, then suddenly music stopped and a message popped up: usb error remove the device and press usb stop button. I rebooted the deck and the message still stays there, i can play music via CDs but cant anymore via usb. When i play music on cds the message still occurs there, what can i do? help please.

Tried a different USB stick? Might just be defective.
